If backuping up a live database from a snapshot is not trustworthy, either the snapshot facility is broken or the database is broken (i.e., not crash-safe to begin with). That said there are plenty of other reasos to use proper dump tools (data portability, confirming the ability to actually read all rows =66rom a table, using a more often exercised code path and perhaps less likely to have edge case bugs, etc). --=20 / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller ' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org --J/dobhs11T7y2rNN Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEARECAAYFAknLirsACgkQDNor2+l1i31ZEgCdEqNBg7vRQorydzFVUmRMFI3H UVcAnA6sie1EgWonOybD7Ce/RRoZ/DgD =3wsx -----END PGP SIGNATURE----- --J/dobhs11T7y2rNN--
